我有一个spring Boot 后端API，我使用以下Configuration对API接收的有效负载进行一些格式化。

@Configuration
class WebConfig : WebMvcConfigurer {
    override fun addFormatters(registry: FormatterRegistry) {
        registerSpringFormatters(registry) //This is a custom method I wrote
    }
}

字符串
现在我需要写一个单元测试来测试控制器接收到的输入是否正确格式化。我为此写了下面的测试。

class MyApiControllerTest {
    private val myService: OrderedProjectVintagesService = mock()
    private val myController = MyController(
        myService = myService
    )
    private lateinit var mockMvc: MockMvc

    @Test
    fun `test comma in attributes`() {
        val input = Request(
            projectTypes = listOf("type1,2"),
        )
        val sortedSummaries = listOf(
            Summary(
                currentPrice = BigDecimal("35"),
                projectName = "Project 1"
            )
        )
        whenever(
            myService.listProjects(
                projectTypes = input.projectTypes!!
            )
        ).thenReturn(sortedSummaries)
        mockMvc = MockMvcBuilders
            .standaloneSetup(productItemOrderingController)
            .build()
        mockMvc.perform(
            get("/api/ordered-projects")
                .param("projectTypes", "type1,2")
        ).andExpect(status().isOk)

        verify(myService, times(1)).listProjects(
            projectTypes = input.projectTypes!!,
        )
    }
}

型
然而，我的测试失败了，因为在测试过程中没有注册WebConfig。我如何让我的测试使用WebConfig正确格式化的输入？
